Study Notes
Solubility Concepts
- A solution is a homogeneous mixture of two or more substances, where one substance (the solute) is dissolved in another substance (the solvent).
Importance of Solubility in Drug Formulation
- Studying the solubility of drugs is important because it affects their absorption, distribution, metabolism, and excretion (ADME) properties, which in turn impact their efficacy and safety.
Critical Solution Temperature
- The critical solution temperature is the minimum temperature above which a solution will not separate into two phases, i.e., it is the highest temperature at which a solution can exist.
Partial Miscibility
- Partially miscible liquids are those that can mix together but only to a certain extent, resulting in separate phases or layers.
Characteristics of a True Solution
- A true solution is characterized by a particle size range of 0-10 nm (nanometers), indicating that the solute is fully dissolved in the solvent.
- A true solution is also homogeneous, stable, and transparent, with the solute particles dispersed evenly throughout the solvent.
Significance of Solubility in Drug Formulation
- Studying solubility in drug formulation is crucial because it affects the drug's bioavailability, pharmacokinetics, and pharmacodynamics.
Distribution Law in Pharmaceutical Sciences
- The distribution law in pharmaceutical sciences describes the partitioning of a drug between two or more phases, such as between an aqueous and a lipid phase.
Consequences of Low Aqueous Solubility
- Drugs with low aqueous solubility can lead to problems with bioavailability, formulation, and efficacy, as well as potential toxicity issues due to inadequate absorption.
